Duma-WAGON.

SPECIFICATION forming part of Letters Patent No. 714,481, dated November 25, 1902. Application filed May 5, 1902. Serial No. 105,991. (No model.)

T @ZZ whom, it Magnan/cern:

Be it known that I, JOHN W. HAYWOOD, of Syracuse, in the county of Onondaga, in the State of New York, have 'invented new and useful Improvements in Dump-Wagons, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in rear axle and the rear end of the box is free to tilt downwardly and rearwardly.

A further object is to provide a suitable brake for holding the rear wheels from movement during the operation of moving the box rearwardly and tilting thesame.

A still further object is to provide a tailboard for the open end of the box, which tailboard is fixed to the support in such manner that the box is free to tilt rearwardly and downwardly between the tail-board and rear axle.

Another object is to provide means for automatically operating the forward end of the box as the same is moved "rearwardly for facilitating the dumping of the load; and a further object is to provide movable means for l locking the box-support and front axle from rearward movement when the parts are in their normal position. ,l

To this end the invention consists in the combination, construction, and arrangements of the parts of a dump-wagon, as hereinafter and other parts of my invention, the tilting box being removed for disclosing the underlying parts. Fig. 4 is a sectional view taken on line 4 4, Fig. 3, the wheels being removed and the box being shown in operative position and in section. Fig. 5 is a transverse sectional View taken on line 5 5, Fig. 4.

Similar reference characters indicate corresponding parts in all the views.

In the drawings I have shown a dumpwagon consisting of front and rear axles 1 and 2, front and rear wheels 3 and 4, mounted on the axles, a frame 5, having its front end mounted on the front axle and its rear end extended beyond and carried by the rear axle, a second frame 6, mounted on the rear axle and extended forwardly therefrom, a dump-box 7, mounted on the frame 5 and extended rearwardly over the rear axle, a tailboard 8, brake mechanism 9, and a detent 10.

The front axle 1 is provided with suitable hounds 11, to which is connected a pole or equivalent device 12, said pole being pivoted at 13 in front of its rear end, and the rear end is arranged to engage the lower face of a head-block 14 for the purpose of holding the pole or thills in their elevated position and at the same time permitting the same to be moved upwardly. This axle 1 is connected to the head-block 14, which forms a portion of the frame 5, by a king-bolt 15, upon which the front axle readily turns in guiding the wagon.

The axle 1 and its supporting-wheels are moved toward and away from the rear axle 2, this movement being eected by the motive power, as the horses, for a purpose hereinafter described.

The frame 5 is mounted at its front end upon the axle 1 and hounds 11 and comprises the head-block 14, transverse bars 16 and 17, secured to the head block, lengthwise substantially parallel side bars 18, having their front ends secured to the opposite ends of the cross-bars 16 and 17 and their rear ends resting upon a bearing 19, carried by the rear axle 2. 4

The rear frame 6 is carried by the rear axle 2 and consists, essentially, of a crossbar 20 and lengthwise substantially parallel side bars-21, extending forwardly from the opposite ends of the cross-bar 2O and united at their' forward ends by an additional cross-bar 22, which is located in front of the rear axle substantially parallel therewith, this latter cross-bar serving to brace the forward ends of the bars 21 against lateral strain.

The tail-board 8 is secured to the extreme rear ends of the bars 18 and serves not only to unite and stiffen the rear ends of the framebars 18, lout also forms a closure for the open rear end of the dump-box,presently described. This tail-board preferably extends above the upper plane of the sidev bars 18 and usually inclines forwardly from its lower edge for permitting the tilting movement of the rear end of the box and is held firmly in position by suitable brace-bars 23, connecting the upper end edges of the tailboard to the side bars 18.

` The brake mechanism 9 may be of any desired construction adapted to prevent the rotation of the rear wheels during the movement of the front axle backward and forward in the act of dumping or returning the box to its normal position. As seen in the drawings, this brake mechanism consists of a main lever 25, pivoted at one end at 26 to the cross-bar 22, additional levers 27, also pivoted at their intermediate portions at 28 to the cross-bar 22, their inner ends being linked to the intermediate portion of the le- Ver 25, and their outer ends are provided with shoes 29 for engaging the periphery of the wheels 4. A suitable lever 30 is pivoted at 31 to the forward end of one of the bars 21, and its intermediate portion is connected by a link 32 to the free end of the lever 25, said lever30 and link 32 being connected in such manner that when the brake is applied the pivotal connection of the link with the lever is in substantially the same straight line with the pivotal connection of the link with the lever 25, so as to form a toggle-lock to hold the brake in operative position.

The box 7 may be of any desired form or size adapted to be used in connection with the rearwardly-sliding frame 5, said box being centrally pivoted at 34 to and between the side bars 18, its forward end normally resting upon the cross-bars 16 and 17, and its rear end rests upon the bearing 19, said forward end being provided with a depending stud 35, arranged to enter a socket 36 in the front bar 16 when the box is in its normal or loading position, this stud and socket serving to lock the box from lateral or lengthwise vibration or movement and also permits the box to be readily tilted when desired.

It is evident from the foregoing description that the frame 5 being locked to the front axle 1 by the king-bolt 15 and the box 7 being pivotally mounted upon the side bars 18 of the frame 5 any forward or rearward movement of the axle 1 toward and away from the rear axle 2 imparts a similar lengthwise movement to the sliding frame 5 and box 7 and also to the end-board 8, which is mounted upon the rear ends of the side bars 18.

The rear end of the box 7 is open, and when said box is in its normal position the endboard 8 firmly engages the end edges of the side walls of the box and is of sufficient width to close theopen end of the box.

Mounted upon the central portion of the bar 22 and upon the lower face of the bottom of the box 7 are inclined bearings 37 and 38, the bearing 38 being adapted to ride upon the bearing 37 as the box is moved rearwardly and automatically elevates the forward end of the box to facilitate the dumping of the load. In order to guide the frame 5 in its rearward and forward movement, I provide the forward ends of the bars 21 with suitable guides or ways 39, arranged in the form of loops, which overlap the lower and upper faces of the bars 18 and prevent any Vertical vibration of the bars 18 and 21. In order to further support the intermediate portions of the bars 18, upon which the dump-box is mounted, I provide the forward ends of the bars 21 with inwardly-projecting roller-bearings 40, which engage the lower faces of the intermediate portions of the bars 18.

The bearing 19, although carried by the axle 2, is preferably mounted in the rear ends of the bars 21 and consists of a roller which is better adapted to facilitate the sliding movement of the frame 5 and dump-box 7 and also forms a convenient support for the box during its tilting movement when the pivots 34 are directly over its axis.

Although, as previously stated, the tilting box is pivoted at substantially its central portion, the heavier end is nevertheless at the rear of the pivot in order that the tilting may be as nearly automatic as possible when the pivot of the box is moved to a position directly over or at the rear of the roller-bearing 19.

The detent 10 may also be of any desired construction adapted to hold the slidingframe and the front axle in their normal positions. As seen in the drawings, this detent consists of a lever having a shoulder 42, arranged to engage a similar shoulder 43, provided upon the upper face of one of the bars 21, said lever being pivoted at 44 to the adjacent side bar 18 of the frame 5, so that when the slid-- ing frame is drawn forwardly by the horses or other propelling power the shoulder 42 automatically drops into engagement with the shoulder 43, the forward end of the lever being extended to a point in proximity to the position of the operator, so that the operator may readily release the detent when it is desired to back the horses to dump the load.

Although I have shown and described a rear-end dump-wagon having front and rear axles and supporting-wheels, it is evident that the essential features of my invention are equally applicable'to two-wheeled wagons, and I do not, therefore, limit myself to the precise construction and arrangement shown and described.
